The Miami Herald (Sarah Rothschild) reports: Ron Culp’s 3,001st game will be his last. The only head trainer the Heat has known in its 20-year history is retiring. Culp, who also serves as travel coordinator, is leaving after Wednesday’s season finale. It will end his run of a record-setting 37 seasons on the job. He started with the 1970-71 Cleveland Cavaliers expansion team and went to Portland in 1974, where he was part of the 1977 championship team, and arrived in Miami for its inaugural season in 1988… Culp is a three-time winner of the NBA trainer of the year award and has two championships on his résumé (including 2006 with the Heat), but his devotion to the players is as much his legacy as his decades of service.
